Test Description

WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers in the diagnostic procedures.

1 - The Diagnostic System Check - Engine Controls prompts the technician to complete some basic checks and store freeze frame data, if applicable. This creates an electronic copy of data taken when fault occurred. Information is then stored in scan tool for later reference.
2 - This step checks for a high input condition. If scan tool reads 284°F (140°C), the input circuit may shorted to the sensor ground circuit.
3 - This step checks for a low input condition. If scan tool reads -40°F (-40°C) the input circuit may be open.
4 - This step checks whether DTC P0110 is the result of a hard failure or an intermittent condition. Operating vehicle in check mode enhances PCM diagnostic capabilities.
